Abstract:
Low Density Polyethylene(LDPE) is considered as an
important material for the insulation in high voltage dc.The
knowledge of conduction current and in LDPE material is quite
vital due to the fact that it is related to charge accumulation in
it.Tounderstand the whole information of conduction current and
space charge accumulation, we have been trying to construct a
new method wherethe measurements are performed using a
guarded three-terminal electrode system.Traditionally, the
measurement of conduction current was done on the ground
electrode due to safety reasons. With the advent of wireless
technology such as Zigbee modules etc, the measurement at high
voltage electrode is also possible. So by taking dielectric sample as
LDPE, we have been trying to find the conduction current and
space charge accumulated in it.
